NEAR-EARTH ASTEROID (152931) 2000 EA107: A PROBABLE BINARY.
CCD photometric observations of the near-Earth asteroid (152931) 2000 EA107 were made in 2019 March and April at the Center for Solar System Studies (CS3). Analysis of the data found that the asteroid is likely a binary. The primary period is P1 = 4.1367 ± 0.0002 h with a lightcurve amplitude of A1 = 0.29 ± 0.02 mag. The secondary period is P2 = 16.079 ± 0.006 h with a lightcurve amplitude of A2 = 0.16 ± 0.01 mag. No mutual events (occultations and/or eclipses) were seen to confirm the presence of a satellite.
